Abstract

In one embodiment, a method includes identifying optical transceivers installed in optical module ports at a network device based on input received at electrical interfaces at the network device, identifying at least one optical module port without an optical transceiver installed, determining if a plug is inserted into the optical module port, wherein an electrical signal indicates insertion of the plug into the optical module port, and raising an alarm if the optical module port is open. Insertion of the plug into the optical module port reduces airflow bypass, electromagnetic interference leakage, and contamination without the optical transceiver installed in the optical module port. The plug is also disclosed herein.
